Anhui Hefei ‘Artificial Sun’ +1: A Major Breakthrough in China’s Nuclear Fusion EnergyRecently, the Experimental Advanced Superconducting Tokamak (EAST), known as the ‘Artificial Sun,’ in Hefei, Anhui Province, set a new world record by achieving a breakthrough in controlled nuclear fusion operation duration, marking a critical step forward in China’s fusion energy research.The ‘Artificial Sun’ simulates the nuclear fusion reaction within the sun, using hydrogen isotopes as fuel to generate immense energy under extreme high temperature and pressure. The core of this breakthrough lies in the device’s success in extending the steady-state long-pulse high-confinement mode operation of plasma to hundreds of seconds, far surpassing the capabilities of similar international facilities. This achievement not only validates the reliability of key technologies such as superconductivity and high-temperature plasma control but also provides essential data for future commercial fusion reactors.As a comprehensive national science center, Hefei—home to the Institute of Plasma Physics under the Chinese Academy of Sciences—has become a global hub for fusion research. EAST’s continuous innovation demonstrates China’s technological prowess in clean energy, offering a promising solution to address global energy crises and carbon neutrality goals. Fusion energy, characterized by abundant fuel, zero carbon emissions, and high safety, is regarded as the ‘ultimate dream’ of human energy, and Hefei’s ‘Artificial Sun’ is turning this dream into reality.
